Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542322, here are decompositions:

41 + 31542281 = 31542322
89 + 31542233 = 31542322
173 + 31542149 = 31542322
239 + 31542083 = 31542322
311 + 31542011 = 31542322
389 + 31541933 = 31542322
419 + 31541903 = 31542322
431 + 31541891 = 31542322

Showing the first eight; more decompositions exist.
